STOP-COCK.

SPECIFICATION forming part of Letters Patent No. 353,5102, dated December 7, 1886.

Application filed March 17, 1886. Serial No. 195,611. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES J. MORTIMER, of New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Stop-Cocks, of which the following is a specification.

The object of my invention is to produce a stop-cock that may be employed either as a self closing cook or as a hand-cock, and which is not only an improvement upon the former kind as heretofore in use, but also has the further novel featurethe combination of these two kinds in one device.

Heretofore the self-closing action of stopcocks has been produced by theuse of aspringactuated valve set in the body of the faucet, and which is operated by vertical pressure on a button or lever, which depresses the spring and opens the water-way. When the pressure is withdrawn, the flow ceases, the spring causing the valve to reclose the mouth of the supply-pipe. Should the tension of this spring decreasefrom use, or for any other reason should the spring fail to act well, the valve will only partially close the mouth of the supply-pipe, and a constant and wasteful flow of liquid will result. By my invention, however, this difficulty is overcome by substituting for the spring a simple contrivance, to be presently explained, which accomplishes the desired result, and is more satisfactory and not as likely to get out of order or to become as readily or at all ineffectual.

In the annexed drawings, forming a part hereof, Figure 1 is a view in elevation of my faucet; Fig. 2, a vertical section of the same, and Fig. 3 a longitudinal section through line so a: of Fig. 2.

A is the body of the faucet, Bthespout, and C the handle. Spout B is joined to body Aat a, and the faucet is connected with the supplypipe at b. There is an opening, a, through body A, which is made continuous with the spout and supply-pipe. In opening 0 is the valve rod or shalt d, to the lower end of which is attached the valve or stopper e, of rubber, leather, or other suitable material, closing upwardly and in the direction of the water-pressure upon its valveseat, as shown.

The upper end of shaft 01 terminates in a rack, 7, which sets in a recess, f, in the upper part of body A, Fig. 2. Through the side of body A, above the spout and at right angles to rack f, is another opening, 0, which meets with.

opening 0, and through which passes a rod, D,

the inner end of which sets in a bearing, 9.

- groove, Z, into or through which passes a pin,

m, on rod D, which pin moves from side to side in such slot by the turning of rod D. Over projection is, pin m, and slot 1 is screwed a cap, a, which prevents rod D, by fitting closely against pin m, from coming out of its inner bearing, 9, but does not interfere with its free lateral movement.

To prevent the liquid from working its way up to and out of opening a, a suitable watertight packing, 0, is placed around rod D in a recess, 1), in body A, just inside projection is, Fig. 3.

The outer end of rod D, protrudingthrough body A and projection k. is made in the form of a square, over which fits the handle 0, Fig. 3, which is kept thereon by a small screw. t.

Handle 0 is heavy or weighted, and is made preferably of solid metal.

The operation of these parts is as follows: In Fig. l is shown-the position of handle 0 when stopper 6 is closing the opening to body A and whena flow of water or other liquid is not desired. By moving handle 0 upward, and thus turning rod D till stopped by pin m in slot Z, stopper 6 is forced from its seat downwardly against the water-pressurc,the teeth of pinion h turning into the notches of rack f, forcing the shaft dandstopper e downward, and permitting a free flow of water or otherliquid from thesnpply-pipe. When the desired amount of liquid is obtained, the hold on handle 0 is released, and it then falls by its own weight, turning rod D, pinion h, and rack f back to their original positions, the valve e being returned to its seat, cutting offthe further flow of water. This movement of valve is assisted by the water-pressure, and hence the weight of handle need not be excessive to make the action certain. It will thus be seen that the self-closing action of the faucet is produced by the falling circle to the position shown by dotted lines at G in Fig. 1 a hand-cock is obtained. When handle 0 is at O, the stopper 6 is closing the opening from the supply-pipe. Moving it to the position shown by dotted lines at O" in Fig. 1, rod D is turned and stoppere is forced from its seat, as before, by the turning of pinion h in rackf. In this case the weighted handle prevents the water-pressure acting on the valve from reclosing the mouth of opening 0, and when the desired amount'ot' liquid is obtained handle 0 is turned back by hand from C to C and the flow ceases, as will be understood.

Fig. lot the drawings representsin full lines a faucet for usein basins,and the portion shown in dotted lines illustrates the modification necessary for use. in sinks, &c.

What I claim is-- 1. A stop-cock wherein are combined with the body and outlet and inlet pipes thereof a valve and a weighted handle connected with said valve and opening and closing the cock by its movement, such weighted handle being adj-ustably connected with the valve-operating parts, whereby the handle can be adjusted to work wholly on one side of the center, so as to return the valve automatically to its seat, or

the handle can be adjusted to work back and forth over the center, so as to hold by its weight the valve in either an open or closed position,

substantially as set forth.

2; A stop-cock wherein are combined with the body and outlet and inlet pipes thereof a valve, a rack connectedwith said valve, a pinion engaging said rack, and a weighted han dle secured adjustably to the spindle of said pinion, whereby the handle can be adjusted to work wholly on one side of the center, so asto' return the valve automatically to its seat, or.
